Description

TECHNICAL FIELD

Embodiments of the present invention are related to identifying an object based upon its geographic location and accessing information about that object.

BACKGROUND

Data collection devices are frequently used to collect and/or update geographic databases. However, these data collectors are typically relatively large and heavy for a handheld device and therefore may be unwieldy for an operator to use. Additionally, these data collectors use a large number of buttons and icons for specific data entry functions. As a result, the operator of one of these data collectors has to be trained to properly use the interface and may have difficulty operating the device, even after receiving this training. Additionally, these data collectors are relatively expensive (e.g., $1500-$5000) and therefore the initial purchase and/or replacement of lost or stolen data collectors is not a trivial investment.

SUMMARY

A method and system are described, which are used to identify a geo-referenced object. In one embodiment, a position determining component is used to determine the geographic position of a handheld electronic device. An azimuth determination component determines an azimuth from the handheld electronic device to an object. An incline measurement device measures the vertical angle between the handheld electronic device and the object. Finally, based upon the based upon the geographic position, azimuth, and vertical angle of the handheld electronic device a database is automatically accessed wherein a description of the object is stored.

DETAILED DESCRIPTION

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. While the present invention will be described in conjunction with the following embodiments, it will be understood that they are not intended to limit the present invention to these embodiments alone. On the contrary, the present invention is intended to cover alternatives, modifications, and equivalents which may be included within the spirit and scope of the present invention as defined by the appended claims. Furthermore, in the following detailed description of the present invention, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, embodiments of the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail so as not to unnecessarily obscure aspects of the present invention.
FIG. 1 is a block diagram of an exemplary handheld electronic device 100 which can be used to identify a geo-referenced object in accordance with embodiments of the present invention. In FIG. 1 a position determining component 110, an azimuth determining component 115, an incline measuring device 120 and a processor 125 are coupled with a bus 101.
Position determining component 110 is for determining the location of handheld electronic device 100. In embodiments of the present invention, position determining component 110 comprises a GPS antenna 112 and a GPS receiver 111. More generally, position determining component is operable to utilize Global Navigation Satellite System (GNSS) radio signals to determine the geographic position of handheld electronic device 100. However, while the present embodiment specifically recites a GNSS position determining component, embodiments of the present invention are well suited to utilize a variety of terrestrial-based and satellite-based position determining components as well. In embodiments of the present invention, the geographic position determined by position determining component 110 describes the latitude and longitude of handheld electronic device 100. However, position determining component 110 may also determine the elevation of handheld electronic device in embodiments of the present invention.
Azimuth determination component 115 is for determining a horizontal angle, relative to handheld electronic device 100, from a reference direction (e.g., magnetic north, or true north) to a geo-referenced object. In embodiments of the present invention, azimuth determination component 115 may detect variations in the Earth's magnetic field, or may utilize a gyroscope to determine true north.
Incline measurement device 120 is for measuring a vertical angle difference between an artificial horizon and an object at which handheld electronic device 100 is pointed. There are a variety of devices which are suitable for measuring an incline in embodiments of the present invention including, but not limited to, tilt sensors and inclinometers. It is noted that in embodiments of the present invention, incline measurement device 120 may measure the tilt of handheld electronic device 100 in more than one plane of motion (e.g., roll and pitch) to more precisely determine the vertical difference described above. Additionally, incline measurement device 120 may comprise a component which automatically determines a level plane of reference which is used as a baseline measurement for measuring the vertical angle described above.
Processor 125 is for processing digital information and instructions and bus 101 is for conveying digital information between the various components of handheld electronic device 100. Also coupled with bus 101 is a random access memory (RAM) 130 for storing the digital information and instructions of a more volatile nature and a non-volatile read only memory (ROM) 135 for storing information and instructions of a more permanent nature. In addition, handheld electronic device 100 may optionally include a data storage device 140 for storing vast amounts of data. In embodiments of the present invention, data storage device 140 may comprise a removable storage medium such as a smart card or an optical data storage device. Alternatively, data storage device 140 may comprise a programmable data storage device such as a flash memory device to facilitate quickly updating data. It should be noted that instructions for processor 125 as well as position coordinates which define a geo-referenced object, previously determined geographic locations of handheld electronic device 100, and previously sampled GPS signals can be stored either in memory 130, ROM 135, data storage device 140, or in an external storage device (not shown).
A wireless communications component 145, comprising a wireless modem 108 and a wireless antenna 109, is also coupled with bus 101. Wireless communications component 145 is for transmitting and receiving wireless messages (e.g., data and/or commands). In one embodiment, wireless communications component 145 is comprised of a cellular wireless antenna 146 and a cellular wireless modem 147. In embodiments of the present invention, wireless communication component 145 is compliant with the Global System for Mobile Communications (GSM) specification. While the present invention recites a GSM compliant wireless communication device, other wireless communication specifications, such as the Global Packet Radio Service (GPRS) specification, may be utilized in embodiments of the present invention. In one embodiment, handheld electronic device 100 sends and receives messages using the Short Message Service (SMS). However, the present invention is well suited to utilize other message formats as well. In other embodiments of the present invention, wireless communications component 145 may comprise a Bluetooth wireless communications device, or another wireless communications device such as a Wi-Fi transceiver. Wi-Fi transceivers are often used to create local area networks between a portable computer and an Internet access point in public areas such as airports, coffee shops, libraries, and the like.
Handheld electronic device 100 further comprises an image capture device 150 and a display device 155 for displaying information to a user. Image capture device 150 may comprise a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) digital image capture device. Display device 155 may be a liquid crystal device, cathode ray tube, a field emission display, or other display device, suitable for displaying graphic images and alpha-numeric characters recognizable to a user. In embodiments of the present invention, a range determining device may also be coupled with bus 101. Typically, range determining device 160 is a laser range determining device. However, other technologies such as sound-based (e.g., ultra-sonic range finders) and optical range finders and may also be used in embodiments of the present invention. It is appreciated that the current description of handheld electronic device 100 is exemplary and that one of more of the above described components (e.g., image capture device 150, range determining device 160) may be omitted in embodiments of the present invention.
A user input device 165 may also be coupled with bus 101 in embodiments of the present invention. In embodiments of the present invention, user input device 165 may comprise a keyboard, and a cursor control device (e.g., a mouse, trackball, light pen, touch pad, joystick, etc.), for inputting data, selections, updates, and for controlling handheld electronic device 100. Handheld electronic device 100 may optionally include a battery 170 for providing power for handheld electronic device 100.
FIGS. 2A and 2B are side and tops views respectively which show the identification of a geo-referenced object using a handheld electronic device in accordance with embodiments of the present invention. In FIG. 2A, a user 201 points handheld electronic device 100 at a geo-referenced object 210 along a sight line (e.g., 222). For the purposes of the present invention the term “geo-referenced object” means an object or geographic feature having a measured geographic position. This can include buildings, dams, bridges, roadways, signposts, markers and other manmade structures as well as geographic features such as mountains, hills, rivers, coastlines, forests, etc. In embodiments of the present invention, image capture device 150 and display device 155 can be used to facilitate pointing handheld electronic device 100 in the direction of geo-referenced object 210. In FIG. 2A, incline measurement device has determined that sight line 222 is oriented at a vertical angle a (e.g., 220) above a reference horizon (e.g., 221). Furthermore, using position determining component 110, handheld electronic device 100 determines its geographic position (e.g., 205 of FIG. 2A).
With reference to FIG. 2B, when user 201 points handheld electronic device 100 at geo-referenced object 201, azimuth determining component 115 determines the azimuth θ (e.g., 250) which is defined as the horizontal angle between sight line 222 from a reference North direction 252 (e.g., magnetic North, or true North).
In embodiments of the present invention, the geographic position 205 as well as the azimuth θ250 and vertical angle α220 are used to identify geo-referenced object 210. In one embodiment, this can be accomplished by processor 125 using object identification component 125 a. In another embodiment, as will be discussed in greater detail below, geographic position 205 as well as the azimuth θ250 and vertical angle α220 are wirelessly transmitted to a remote server which is operable for identifying geo-referenced object 210 based upon this information. In embodiments of the present invention, additional data may be input to handheld electronic device 100 by user 201 using data input device 165. This additional data may be used to generally identify which geo-referenced object user 201 is trying to identify. For example, referring again to FIG. 2A, user 201 may input that geo-referenced object 210 comprises a mountain rather than building 240 which may generally lie along sight line 222, but which is not the intended object being identified. Additionally, range determining component 160 may be used to determine the distance, conventionally shown as 222, between handheld electronic device 100 and geo-referenced object 210.
In embodiments of the present invention, after geo-referenced object 210 has been identified, a database (e.g., 320 of FIG. 3), where a description of the geo-referenced object is stored, can be accessed. In embodiments of the present invention, database 320 can be accessed wirelessly by handheld electronic device via communication network (e.g., 310 of FIG. 3) using wireless communication component 145. The description of the geo-referenced object may include, but is not limited to, geographic position information (e.g., latitude and longitude), elevation data, physical data, historical data, pictures, multimedia information, and other data types such as lot number, address, name, etc. In embodiments of the present invention, handheld electronic device may be used to edit or update information in database 320. As described above, it is appreciated that occasionally, two or more objects may be indicated based upon the geographic position 205, azimuth θ250, and vertical angle α220 of handheld electronic device 100. Accordingly, in embodiments of the present invention, database 320 may initially return a plurality of results to an inquiry by handheld electronic device 100. For example, with reference to FIG. 2A, an initial return from database 320 may list building 240 and geo-referenced object 210. User 201 may then select which of the objects is to be identified.
In another embodiment of the present invention, handheld electronic device 100 further comprises an object identification component 125 a. In embodiments of the present invention, some, or all of, the data stored in database 320 may be stored in handheld electronic device 100 (e.g., in data storage device 140) and accessed by processor 125 upon activation of handheld electronic device 100). It is appreciated that in embodiments of the present invention, the data comprising object identification component 125 a may comprise a subset of the data comprising database 320. In embodiments of the present invention, when processor 125 accesses the geographic position 205, azimuth θ250, and vertical angle α220 of handheld electronic device 100, it uses object identification component 125 a to identify and/or access a description of geo-referenced object 210.
FIG. 3 shows a system 300 for identifying a geo-referenced object in accordance with embodiments of the present invention. In the embodiment of FIG. 3, system 300 comprises handheld electronic device 100 which is communicatively coupled with database 320 via wireless communication network 310. Utilizing a wireless communication network is advantageous in that handheld electronic device 100 may be implemented as a portable data collector in a manner similar to a GIS data collector. In the embodiment of FIG. 3, identification component 125 a is a component of a computer 340 communicatively coupled with network 310 and database 320. It is appreciated that handheld electronic device may also be communicatively coupled with another computer network (e.g., via a wired or wireless communication network) in embodiments of the present invention. It is further appreciated that additional components have been omitted from FIG. 3 for clarity.
